I'll do 1 and 8, and you should then be able to do 2 and 9!
For 1, we can multiply these separately - 3*4*9=108 and 5+7+2=13 (exponent multiplication is adding them!), so we have 108b^13
For 8, we can again add the exponents up to get (5/7)^8

Answer: Mean: 9
MAD: 46
Step-by-step explanation:
I will show u how to work out the mean
and the mad so u know
MEAN:
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.
MAD:
1) To find the mean absolute deviation of the data, start by finding the mean of the data set.
2 )Find the sum of the data values, and divide the sum by the number of data values.
3) Find the absolute value of the difference between each data value and the mean: |data value – mean.
